What Did The 1968 Race Hemi B029 Barracuda or LO23 Dart Run 'out of the box'.

You said "no modifications". They did not come with 10.5 slicks. As delivered I would say high 14's because of traction issues.

They rolled out of the Hurst Facility with 7.75 x 15" Rear Tires for transportation purposes. Some were lucky, and got 8.25 x 15" Rear Tires.

Cars Magazine got their hands on an LO23 4-Speed in March 1968, to do a 'black & white' photo shoot at Detroit Dragway.

Jerry Gross of Chrysler, was brought along as the 'test driver'.

With an 8-Quart 'deep' Oil pan, and Goodyear 10.5" Slicks on Cragar 'chrome-plated' stock 15" x 8" rims, he posted '2' runs in the 11.40's @ 120 MPH.
